For this week’s exercise, the HVAC system are created. Two major thermal zone are designed which is floor 0 and 1, floor 2 and 3. Specifically, 14 minor thermal zones are designed for the whole building for individual control for temperature.
For heating strategy, by considering the geological conditon of the building, there is less heating loads are need for this building. Thus, rooms facing south will gain more solar energy and have less energy cost for heating. For cooling strategy, sunshades facing south are provided to reduce cooling loads for the buidling. Two air units are provided for each major thermal zone to provide sufficient cool air to maintain habitable temperature to keep visitors’ experience good.
The major challenge for the design is the calculation of heating and cooling loads. Because of the large area of glass curtian wall, rooms have different cooling and heating loads that needs to be consider with different schedules.
Your Design Journal entries for this module should highlight your design thinking and analysis results that influenced your decisions about:
- your overall HVAC system strategy
- your heating strategy and how you implemented it in your design
- your cooling strategy and how you implemented it
- any special HVAC system challenges that you encountered
